Claims.

This invention relates to the supporting of Web rolls for supplyingprinting presses with webs, although it is capable of use in otheranalogous arts.

The principal object of the invention is to provide practical means formoving the individual supporting means for a new web roll into positionto pick up the new Web roll without moving the rest of the supportingmeans which carries the running roll.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which 155. Fig.1 is an end view of a rotatable reel for carrying web rolls constructedin accordance with this invention, and

Fig. 2 is an elevation of the same.

The ordinary practice in supplying web rolls to printing presses is tobring the new roll into position on a dolly or small truck and to jogthe reel back and forth until the arms which are to carry the new roll,or rather the centers for supporting the new roll, coincide with thecenter of the roll on the truck. This jogging of the reel back and forthis done necessarily, in the most up-to-date practice, while the paper isbeing fed at full speed from another roll carried by the same reel. Itis a well-known fact that the jerking of the running web roll is apt toresult in the breaking of the paper being fed therefrom.

The purpose of this invention is to provide means whereby the runningroll can be maintained on a stationary axis while a part of the reel ismoved back and forth for the purpose of centering it with respect to anew roll. The invention is shown as applied to a rotary reel which isordinarily used for this purpose but is capable of application to anoscillating support for the rolls as well.

As in ordinary practice, a pair of pedestals 10 carry a shaft 11 whichis rotated through a worm wheel 12 from a motor or other source ofpower, not shown. In this case, the shaft is provided with two hubs 13,adjustably secured to it usually, to provide mountings for the severalpairs of arms 14 which are pivotally mounted on the hubs on shafts 15and constitute pivoted frames for carrying one roll apiece. On one ofthese hubs are mounted motors 16 equal in number to the number of frames14. These are reversible motors connected up so as to be operated ineither direction controlled by push-buttons at will.

Through suitable gearing, they drive worms 17, 5 which in turn driveworm wheels 18 on respective Wood, New York, N. Y., assignor Y., a.corporation of Corporation, Virginia Machinery 1932, Serial No. 599,720(01. 242-64) shafts 19. Each shaft is provided with a pinion 20 meshingwith a gear segment 21 which is made integral with each one of the arms14.

Three pairs of arms are indicated, located at opposite ends of thedevice and the arms are provided with centers which support the spindlesof the web rolls. In the case shown, one spindle is supporting therunning web roll R, there is a spare roll R which has previously beenloaded on the reel, and a roll R is shown on a truck 22 in position tobe loaded. For the reasons stated, it is not desired to shift theposition of the running roll R while this new roll R is being loaded onthe reel. Consequently the motor 16, which corresponds with the pair ofarms 14, which are to be used to support the roll R is set in motion forthe purpose of shifting this frame 14 through the gearing described.That pair of arms 14 is moved into position so that the centers carriedthereby will coincide with the axis of the roll R This position isindicated in dotted lines in Fig. 1.

Having brought this pair of arms into registration with the center ofthe roll, the proper action is taken to mount the roll thereon and thenthe motor is turned in the opposite direction to bring the arms 14 outinto a radial full line position, as it is intended that all of thesearms shall be located radially when in operation. The worm 17 of courseprevents the arms from being moved out of radial position after oncebeing moved into it, except by the operation of the motor. Thisconstruction can be used also to adjust the position of the arms at anytime if they do not happen to be in the right position.

In this Way it will be seen that the new roll can be picked up withoutdisturbing the position of the running roll, thus avoiding all paperbreaks heretofore caused by the operation of moving the whole reel backand forth.

Although I have illustrated and described only one form of theinvention, I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore, I do not wish to belimited to all the details of construction herein shown and described,but what I do claim is:-

1. In a movable support for a plurality of web rolls, the combination ofa plurality of pairs of arms, each arm having means for centering andsupporting one end of a web roll, said arms being movably mounted onsaid movable support, and means carried by said support for moving eachpair of arms individually for the purpose of lo Zr eating them inposition to pick up a new web roll.

2. In a reel for supporting web rolls for supplying printing presseswith paper, the combination of a central supporting shaft and aplurality of pairs of arms projecting therefrom, each pair having meansfor supporting a web roll between them and each pair of arms beingpivoted on pivots parallel with the axis of the shaft, and means forturning each pair of arms individually as needed into position to pickup a web roll so asto be carried by said reel.

3. In a reel for supporting web'rolls, the combination with a rotatableshaft, a pair of hubs mounted on said shaft near its: opposite ends,aplurality of shafts parallel with. the. first shaft and carried by saidhubs, an arm carried on each of the last named shafts and constituting aframe.

for carrying a web roll, and means mounted on the hubs for turning anyone of the last-named. shafts on its own axis for operating the arms,for the purpose described.

4. In a reel for supporting web rolls, the combination of a rotatableshaft, a pair of hubs fixed thereto, a plurality of frames forsupporting web rolls pivoted on said hubs, a series of motors carried byone of the hubs, and means operated by each motor for turning one ofsaid frames on its pivots, for the purpose described.

5. In a reel for carrying web rolls, the combination of a central shaft,a pair of hubs carried by' the shaft, a plurality of frames pivoted onsaid hubs, each frame adapted to carry a web IiOlLJZWO segmental gearson each frame, a series of motors carried by one of the hubs, a pinionmeshing with each of. said segmental gears, and means operated by eachof said motors for rotating two of said pinions for the purpose ofturning a frame on itsaxis.
